As i said, I have no time today but did want to show just one - more than fits your requirements. The ham selling has an 80 ft crankup in the back yard. Well under your budget:
$390,000
Price cut: -$25,000 (7/29)
2700 sq ft 4 BR/3 Bath
"Has seclusion and privacy on an acre lot without the deed restrictions and fees. Do you need a place to park your boat or recreational/work vehicles? Are you looking for a house with a potential mother-in-law suite or a home office with separate entrance? Then this could be just what you are looking for! This home features a 1000 sq. ft. addition with separate entry, 2 ex-large bedrooms, both with huge closets plus a 1/2 bath."
More (Many more) to follow.
Having followed this thread for a bit, based on some of KSP's previous comments on other threads as to his retirement home requirements, there are some that haven't been addressed:
1. Is the home rural, or within reasonable distance to retail, restaurants, entertainment, health care, religious institutions, etc?
2. When was the home built? Does it have the latest building requirements/codes, construction, and energy efficiency?
3. Does it have municipal water, sewer, gas, cabled high speed internet, trash collection?
4. An acre is a lot of ground. Does he want the outdoor maintenance required for that in his retirement?
5. Maybe he can interject some that I have missed.
Being retired myself, and living in the Phoenix area of AZ (very similar to Florida housing), I completely understand KSP's frustrations. Even with a $500,000 budget, EVERY subdivision built out here in the last 25-30 years having his requirements are saddled with antenna restricted CC&R's, HOA enforced or not. And I get the impression he wants something built in the last 10 years or so. Buying a piece of land with NO CC&R's or other restrictions means "rural", and bringing utilities to that land has enormous costs before you even start building.
I'm not trying to be contrary...just relating what I've experienced living in AZ for the last 26 years. Finding a suitable ham antenna-friendly home is not as easy as it seems to some. Compromises are necessary, even at $500,000.
